We claim:

1. In the art of building construction, pre-cast composition wall units each provided with marginal lateral flanges facing the interior of the structure, the vertical flanges of the abutting units being oflset relatively to provide vertical apertures extending to the interior surface of said structure, a separator of resilient material 'located in each of said apertures, one face of said separator extending substantially flush with said interior surface, the remainder extending into the latter a distance less than the depth thereof, thereby providing vertically extending chambers arranged between the laterally adjacent units and behind said separators.

2. In the art of building construction, precast composition wall units each provided with marginal lateral flanges, the vertical flanges of the abutting units being offset relatively to provide vertical apertures, a separator of resilient material located in each of said apertures, said units being joined together by tension members thereby binding said separator between said units and sealing the joint which lies between said units.

3. In the art of building construction, precast composition wall units each provided with marginal lateral flanges, the vertical flanges of the abutting units being offset relatively to provide vertical apertures, a separator of resilient material located in each of said apertures, said units being joined together by bolt-and-nut elements thereby binding said separator between said units and sealing the joint which lies between said units.

4. In the art of building construction, pre-cast composition wall units each provided with marginal lateral .flanges, the vertical flanges of the abutting units being offset relatively to provide vertical apertures, a separator of resilient material located in each of said apertures, a continuous length of reinforcing material extending laterally of each of said units and angularly into said marginal flanges, said units being joined together by tension members thereby binding said separator between said units and sealing the joint which lies between said units.

5. In the art of building construction, pre-cast composition wall units each provided with marginal lateral flanges, the vertical flanges of the abutting units being offset relatively to provide vertical apertures, a separator of resilient material located in each of said apertures, said unitsbeing joined together by tension members thereby binding said separator between said units and sealing the joint which lies between saidv units and relatively plastic elements arranged at each side of said flanges and serving as engaging devices in' conjunction with said tension members.

6. In the art of building construction, pre-cast composition wall units each provided with marginal lateral flanges, the vertical flanges of the abutting units being offset relatively to provide vertical apertures, a separator of resilient material located in each of said apertures, said units being joined together by tension members thereby binding said separator between said units and sealing the joint which lies between saidunits and lead washers arranged at each side oi said flanges and serving as engaging devices in conjunction with said tension members.

7. Inthe art of building construction, pro-cast composition wall units each provided with marginal lateral flanges, the vertical flanges of the abutting units being offset relatively to provide vertical apertures, a separator of resilient material located in each of said apertures and extending into the latter a distance less than the depth thereof, thereby providing vertically extending chambers arranged between the laterally adjacent units and behind said separators, said units being joined together by tension members thereby binding said separator between said units and sealing the joint which lies between said units, the latter extending thru the vertical flanges of said units intermediate said separators and the outer face of said units.

8. In the art of building construction, pre-cast composition wall units each provided with marginal lateral flanges, the vertical flanges of the abutting units being offset relatively to provide vertical apertures, a separator of resilient material located in each of said apertures and extending into the latter a distance less than the depth thereof, thereby providing vertically extending chambers arranged between the laterally adjacent units and behind said separators, said units being joined together by tension members thereby binding said separator between said units and sealing the joint which liesbetween said units, the latter extending thru the vertical flanges of said units intermediate said separators and the outer face of said units and sheets of relatively plastic sealing material arranged between laterally adjacent units at the other faces of said units.
